lack of leadership on this issue. >> how anybody can run for the highest office in the country where 48,000 people are going to get killed in the next four years and not have a plan. people say, well, you shouldn't address it now because we're in a time of crisis and mourning. yeah, well 18 months since arizona, and we did nothing. if not now, when are you going to do this? >> tonight, james holmes remains in solitary confinement in the county jail. i'm joined by nbc news' mike taibbi who is outside the courthouse in colorado. good evening, my friend. >> good evening, professor. how are you? >> i'm doing fine. where does the investigation stand right now? >> well, right now, you can guess, and this is always the case in instances like this, they're trying to build a watertight case in an instance where everything seems pretty obvious. no question who the identity was of the shooter, but he still is the alleged shooter. he's not even the accused suspect yet. he's just a suspect. he won't be formally accused until next monday.
